Visual search and target-directed action.
There have been many investigations of people's ability to search for and detect the presence of identity-defined targets in cluttered visual scenes. Such identity search tasks do not adequately represent those situations in which directed actions must be made to targets. Vision for identification...

Tipper, Steven P. su: Tracking & trailing Movement, Psychology of sug: subj: Tracking & trailing Movement, Psychology of ab: There have been many investigations of people's ability to search for and detect the presence of identity-defined targets in cluttered visual scenes. Such identity search tasks do not adequately represent those situations in which directed actions must be made to targets. Vision for identification and vision for action are processed in parallel, so action processing of all potential target stimuli proceeds until identification processes distinguish the target. Resulting visuomotor competition from distractors can have measurable behavioral effects on the performance of target-directed actions. Such effects are reported here for a task in which human participants reached for red targets in the presence of yellow distractors. The experiments were designed to show that increases in reaching response time could be attributed to visuomotor processing of distractors.
